Usb hdd 3.0 / 2.0

Recently purchased a new Western Digital My Passport Essential WDBACY5000ARD-NESN USB 3.0/2.0 500GB for backup. I have several Wii's that work with a Western Digital My Passport Essential SE - WDBABM001BBK-NESN 1TB. My problem is when i plug in my new HDD 3.0/2.0 it is not recognized. Yet the 2.0 HDD works fine. Both have been formatted with WFBS. Any insight is greatly appriciated.

and this has something to do with a modchip, yes? How about post in the correct forum area instead, thread closed.
